Abstract
A pressing roller formed by extruding a circular mould in a high-density mode through biomass briquette fuel comprises a pressing roller shaft arranged at two ends of the pressing roller and a pressing roller cover in the middle of the pressing roller, wherein the surface of the outer circumference of the pressing roller cover is provided with uniform tooth grooves, widths of two ends of the pressing roller shaft are the same, and the width of the pressing roller cover is between 90mm-100mm. The widths of the two ends of the pressing roller shaft are the same, so when the tooth grooves of the pressing roller cover in the middle portion of the pressing roller are partially abraded, the pressing roller can be installed from a different direction and continues to be used. After the width of the pressing roller cover is narrowed, contact pressure between the pressing roller and the circular mould is reduced, a bearing in the pressing roller is not prone to be burnt and broken, and service life of equipment is prolonged.
